Abstract

A multiplexed, synchronized Active (micro) Lens(let) Array and display providing a user or manufacturer with the ability to choose different modes of functionality of a transparent optical module, such as three-dimensional virtual image generation, two-dimensional image generation, static MLA functionality, augmented, mixed, or enhanced reality, variations in brightness, and other modes.

Description

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention is directed to various ways to realize an Active (micro) Lenslet/Lens Array (“aMLA”), including system functionality utilizing such aMLAs, and related systems and operations.
The present invention is further directed to operation of a near eye augmented reality (“AR”), mixed reality (“MR”), extended reality, enhanced reality, or virtual reality (“VR”) system that combines the virtual image generated by the near eye display with the real world environment taking into account, for example, the visual processes of the retina, the visual cortex, and the oculomotor system. Specifically, the current invention is directed to transparent or nearly transparent optical module (“TOM”) architecture, which is built and/or configured in a manner to provide system scalability in higher resolution and later field of view and eye box. However, the invention herein can be directed to other near eye display architectures and optical solutions that comprise transparent display and aMLA for presenting an image overlaid with a real world view.
The present invention also is directed to a synchronization, in cases temporal synchronization, between the aMLAs and the display so that the two work together in concert to provide a user or manufacturer with the ability to choose different modes of functionality of the TOM, such as three-dimensional virtual image generation, two-dimensional image generation, stereo image formation, static MLA functionality, augmented or enhanced reality, variations (and adaptation) in brightness, and other modes including those described herein.

Description of the Related Art

Currently existing AR or MR systems in most cases have several shortcomings including, but not limited to, large shape/form factor, awkward wearability and utilization (due to problematic human egronomics,) heavy hardware, uneven weight distribution, high power demand (due to low optical/light efficiency), thermal limitations, insufficient brightness for operating in daylight, and/or high price (and cost to manufacture). For these systems to have an increased level of adoption, a transformational technology change or innovation is needed to improve what is currently available. In addition, it is important that any such innovation can be easily adapted to current, established eyewear and ophthalmic lens manufacturing and distribution. The innovation disclosed herein teaches such a transformational breakthrough for the AR and MR industries. In this regard, the current innovation can also be used with virtual reality and extended/mixed reality.

SUMMARY OF THE INVENTION

In embodiments of the present invention, a transparent optical module (“TOM”) system or device comprises an optical architecture hierarchy based on a patch unit. In aspects, the module may be transparent, transmissive, partially transparent, partially transmissive, opaque, partially opaque, or combinations thereof. In aspects, the patch unit comprises one or more regions of display pixels, or a pattern(s) or pixels, and an associated 2D array of small micro lenses (generally referred to herein as “lenses,” “lenslets,” or “micro lenses”), for example on an aMLA. (Herein, the terms lenslet, lens, and micro lens are used interchangeably with regard to the aMLA.) The lenslet is capable of collecting some or most of the light from the display pixels and transmitting that display-emitted light to an eye of the wearer of the TOM which then focuses the light to form a retinal image, which is seen or perceived by the wearer. The Display+MLA+eye together function to construct a virtual image that may appear (to the user looking through the display) to have come from infinity (far field), near the person (near field), or anywhere in between. Multiple TOMs can be combined to provide multiple (virtual) image planes and places. Alternatively, a single TOM with a variable MLA focal length (e.g., having focal plane diversity), can be used to generate for the user a perception of multiple image planes by varying the effective focal length of the MLA in time. Finally, both of the above methods maybe combined to realize additional focal plane diversity which can, for example, create a perception of a three-dimensional (3D) image(s), further enhancing the immersion effect of the display described herein.
In embodiments, regarding a vergence accommodation conflict, the above embodiment allows for resolving the vergence accommodation conflict by, for example, adjusting the virtual (lateral) location of the augmented reality images, as perceived by the eye, in proportion to their perceived distance. For example, as the virtual objects move from infinity (e.g., far field) closer to the viewer (e.g., to “near field”), their perceived lateral distance will also be adjusted (reduced) to overcome the vergence accommodation conflict.
In embodiments, the patch units can be combined further into patch groups, wherein members of a group serve a similar role in retinal image production as a patch unit and/or lenslet. This hierarchy allows the system to be scaled to larger and more complex systems, while maintaining lower complexity and lower cost via standardized TOM module bases.
Accordingly, TOM architecture is built in a manner that provides system scalability. In general, there are two basic elements of TOM architecture as described herein: a patch unit (optical) and a patch group (layout). A lenslet focuses a display pixel or patch to a retinal spot or portion. The lenslet field of view supports imaging an area of an xLED display, such as a pixel patch, and in aspects, “xLED” may be used to refer to, cover, or describe, but is not limited to: OLED (organic Light Emitting Diode), TOLED (transparent OLED), microLED (also μLED and mLED), iLED (refers to microLED, inorganic LED), PMOLED and AMOLED (Passive Matrix and Active Matrix OLEDs), QD-LED (quantum dot LED), or combinations thereof.
A lenslet and its corresponding pixel patch will generally be referred to herein as a patch unit. In aspects, multiple patch units are used to build a larger mosaic image on the retina. Due to magnification, a sparse set of patches and lenslets (i.e., patch unit(s)) can produce a full image as perceived by a user; accordingly, patch units are capable of being sparsely distributed due to magnification. In aspects, the display pixel patches form a sparse microdisplay. In aspects, patches of high density display pixels separated from one another by large areas free of pixels provide for a display or optical module that is highly transparent, allowing for low obstruction see-through viewing.
The intermediate area between primary patch units allows inclusion of additional patch units to provide extra functionality. Sets of patch units that produce retinal images that overlay each other (or in cases are separate or projected side-by-side on the retina) are sometimes defined herein as a patch group. In aspects, patch units are configured so that lenslets do not overlap. In cases, it may be necessary to shield light to control stray light transmitted in between lenslets or potentially couple to neighboring lenslets. Since patch units in a patch group can act individually, in aspects, a patch unit or units can be illuminated independently (in aspects, in both space and time), to support different functions. A grid of patch units can be rectangular or hexagonally packed or any other shape. Rectangular packing, in cases, simplifies some aspects of determining how to decompose the digital image data into sub-images. The notion of the patch unit and patch group or group of pixel patches applies to both static and active MLAs. In aspects, an aMLA may refer to, cover, or describe one or more of:

switchable MLA as understood by one of ordinary skill in the art, such as switchable between two states as described herein;
tunable MLA as understood by one of ordinary skill in the art, such as allowing two states and also having the capability of having intermediate lens states, including a range of tunable focal length(s);
electrically switching lenslets;
nematic phase liquid crystal-based lenslets;
smectic phase liquid crystal-based lenslets;
liquid crystals (“LC” or “LCs”);
cholesteric liquid crystals;
polymer encapsulated or dispersed liquid crystals;
nano-scale polymer encapsulated or dispersed liquid crystals;
blue phase liquid crystal-based lenses;
electrowetting lenslets;
electrostatic lenslets;
ferrofuidic lenslets;
dielectrophoretic lenslets;
pressure actuated liquid lenslets;
micro-mechanical variable focus lenslets;
elastomeric membrane lenslets;
mechanically stretchable lenslets;
chemically ion activated lenslets; and/or
acousto-optical lenslets.

In embodiments, the invention is a system for producing an image including a see-through near eye optical module comprising a see-through near eye display and a micro-lenslet array, wherein the see-through near eye display comprises a plurality of light-emitting pixels or pixel patterns and the micro-lenslet array comprises one or more lenslets; wherein the plurality of light-emitting pixels are configured as a pixel patch; wherein a pixel patch in optical communication with (e.g., associated, coupled, or combined with) the one or more lenslets is configured as a patch unit; and wherein the see-through near eye display and the micro-lenslet array are capable of permitting light rays from a physical object in an external, real world environment to pass through the see-through near eye optical module to the user's retina. The light from the display and the light from the real world external environment, when combined together, are capable of generating augmented reality, mixed reality, enhanced reality, extended reality, virtual reality, etc. In aspects, the TOM and/or optical module is hermetically sealed. In aspects, hermetically sealing provides resilience with respect to ingress of water, air, UV light, and other unwanted things.
In aspects, the patch unit will include an aMLA that is capable of being turned “on” and “off.” In the “off” configuration or mode, the aMLA can effectively act as a see-through window; for example when voltage (or current) is not applied (e.g., the system in naturally in an “off,” i.e. transparent, state) and the lens is in a relaxed state. In some cases, if the aMLA is turned “on” constantly—such as by application of a voltage or current that changes an aMLA or aMLA lens index of refraction, form factor, curvature, shape, diffraction period, or combinations thereof—without cycling between “on” and “off,” the aMLA will effectively act the same or similar to a static MLA as described herein. In aspects, a lens of the aMLA may comprise a conventional, a Fresnel, or a diffractive lens, wherein the shape (or optical prescription, e.g., design) of the lens can be spherical or aspherical.
In aspects, the aMLA will be synchronized (in aspects, in time) to the display so that the display (e.g., in some cases a pixel or pixels as described herein) may pulse light to coincide with an “on” mode of the aMLA. For example, in some embodiments, when the aMLA is turned “off,” a user will be able to see through the TOM to the external environment, and when the aMLA is turned “on,” a user will see a virtual image overlaid with the external environment. Because the eye-brain connection merges the external environment images with the pulsed virtual images, like it does to other multiple static image frames when viewed in rapid succession, such as a motion picture (e.g., movie or video), the TOM is capable of providing, for example, AR or MR that is seamless or nearly seamless (e.g., continuous) in appearance. More specifically, the synchronization between the display, such as a pixel, pixel patch, or patch group, and an associated aMLA(s), in aspects configured as a patch unit, causes the display to activate after or as soon as the aMLA is complete with its “rise time” and is in its “on” mode with a desired focal length (or optical power). Accordingly, the display will activate such pixels, pixel patches, or patch groups when the aMLA reaches its desired focal length (or optical power), creating a virtual image and therefore an AR/MR experience to a user. Pulsing the TOM allows for increased allowance of time for heat dissipation, and an increased perception of virtual image brightness (i.e., a higher value of nits), at a lower energy demand than that of an equivalent continuously emitting display, among other things as described herein. In other aspects, an additional feature of the variable/tunable focal length (optical power) of the aMLA is its ability to be tuned to adapt/compensate for eye imperfections and specifically for near and far sightedness so that people with optical prescriptions may be able to calibrate their aMLA-based AR devices to fully or partially compensate for their prescription. Both spherical/power and astigmatism can potentially be compensated for by adjusting the effective optical power that the aMLA is capable of achieving in its “on” state.
In embodiments, it is possible (and in aspects advantageous) to adjust for each and every (projected) frame, the ratio of “on” to “off” time interval (e.g., “duty cycle”) of the aMLA and the display, changing the ratio from being “on” more or most of the time to being “off” more or most of the time. With the ratio being more or mostly “off” than “on,” the display will provide more transparency, whereas having the display being more or mostly “on” than “off” will provide an emphasis on projecting the virtual image, thereby increasing its brightness as perceived by the user's eye. This can aid in an ability of the invention described herein to rapidly and seamlessly adjust/adapt to changing external brightness or ambient light levels such as, for example, when a user is exiting a dark environment and entering a well-lit environment when, for example, exiting a building, and vice versa. In aspects, this “on” to “off” cycle is called a “duty cycle,” and the duty cycle can be dynamically and automatically adjusted depending on the ambient light environment. Thus a ratio of “on” to “off” state may be increased and thereby enhance a perceived brightness of the image or portion of an image provided by the display pixel(s), which is advantageous in a brightly lit ambient light environment. In a dimly lit environment, the ratio of “on” to “off” may decrease, allowing more light from the real world environment to pass through to a user's eye while also not creating such bright virtual image. The system allows these adjustments, in embodiments, at the patch unit level, the patch group level, the overall display level, and combinations thereof.
This temporal modulation between aMLA and display also allows for the TOM to be able to switch between different modes, such as, by way of example only, a two-dimensional mode, a three-dimensional mode, a window mode (i.e., a see-through window to an external environment without virtual imagery), a peripheral mode when additional information is displayed on the periphery of the abovementioned window (similar to how most cameras display exposure/histogram and other settings on the bottom or side of the frame to aid the user in setting a proper exposure), a “zoom in” and/or “zoom out” mode, a variable brightness mode, and other modes of varying functionalities that differentiate the system from currently available AR, MR, or VR technologies.

DETAILED DESCRIPTION

Reference will now be made in detail to various exemplary embodiments of the invention. It is to be understood that the following discussion of exemplary embodiments is not intended as a limitation on the invention. Rather, the following discussion is provided to give the reader a more detailed understanding of certain aspects and features of the invention.
According to embodiments described herein, there are various optical terms and parameters that describe operation and performance of an aMLA in optical communication with a pixel patch (e.g., “patch unit”). These terms include, but are not limited to, magnification, field of view (“FOV”), resolution, and visual acuity, by way of example. Some of these parameters may influence the optical design and manufacture of the lenslet as described herein, or as would be understood by one of skill in the art.
Further, factors such as the aMLA performance and stray light generation can have an influence on the design FOV. For example, an aspherical lens surface form may be necessary to improve imaging quality for pixels near an edge or extreme edge of the patch unit FOV. Additionally, the aMLA pitch and/or optical power can be designed to vary from the center to the edge of the lenslet array to help improve imaging properties (through minimizing Coma and other aberrations) from the periphery of the pixel patch. The patch unit (or patch units working in concert) FOV according to preferred embodiments described herein is designed to produce an image that can fill the high-resolution foveal region of a user's retina. The FOV in aspects can range from a 10-degree full angular field up to larger values (or smaller values, if needed). Therefore, multiple patch units and/or patch groups can be used to produce a complete wide-angle view.
In embodiments described herein, magnification may describe the relationship between the angular extent at the retina versus that of the display pixel patch or patch unit. In a possible embodiment of a transparent optical module (“TOM”) design described herein, an image magnification is preferably about 7× to 10×, whereas a single lens, single display virtual reality system would have a magnification closer to 1.
The visual acuity of the eye refers to the clarity of vision and ability to recognize detail as described herein or as would be understood by one of skill in the art. The typical eye is able to detect about 1 arc minute angular resolution and is sometimes presented in the form of a measurement, such as 20/20 vision. The visual acuity (e.g., Image Quality (“IQ”)) depends on the retinal resolving elements (rods and cones), aberrations from the eye's lens, and diffractive effects due to aperture size as well as the magnitude of the present stray light in a form of haze, etc. Scattered light, haze and other forms of spurious (stray) light can detrimentally affect Image Quality (IQ) and need to be considered and minimized and/or suppressed. The objective of the TOM as described herein is to present information that is a suitable or preferable match to the eye's visual acuity. For example, text should be sufficiently sharp and sufficiently large to be readable, while images should provide preferably well-resolved features. The application of the TOM and system described herein will in aspects determine the visual acuity level that the display, system, or TOM is able to achieve.
The stray light for an aMLA differs from a static MLA. In embodiments, an aMLA is expected to be “on” for only a fraction of time as a wearer uses the TOM described herein. During this switched “on” time, the aMLA operates as a set of lenslets while the display is synchronized to emit light and provide a virtual image or portion of a virtual image. During the switched “off” state, in aspects, the MLA has no optical power and therefore behaves as though it is a conventional transparent window, and the display does not emit light. During the “on” state, the stray light situation will be the same or similar as for a static MLA. However, when the aMLA is switched “off,” typically less stray light will be present compared to a static MLA.
Since, in aspects, the aMLA needs a finite time to transition from “off” to “on” states, and vice versa, it is preferable to minimize the time between transitions, because during the transition time the aMLA is in a transient state, which can distort the image of the real-world environment that passes through the aMLA, resulting in haze and stray light. In embodiments herein, the “on”-“off” and “off”-“on” transition times preferably range from sub milliseconds (micro-seconds) to a few milliseconds. The “off state is achieved, in embodiments, by allowing the lens(es) to relax, such as when a voltage (or current) is removed from the activating mechanism of the aMLA, or, alternatively, a reverse voltage (or current) is applied. (The “on” state in this example would occur by applying a voltage to the lens.) However, in aspects, the “off” state can be achieved by applying a voltage, while the “on” stage occurs by removing voltage or applying a reverse voltage (or current.)

EXAMPLES

System Operation

In embodiments, the timing of the activation of the aMLA and the emission of the micro display located in its focal plane is such that each individual image “frame” begins by triggering the aMLA to turn “on” in order to generate a preset focal length value or optical power. Regardless of the aMLA technology (as described further herein or as would be known to one of ordinary skill in the art), typically there is a short time period that the aMLA requires to transition from an “off” (e.g., plane window) state to an “on” (e.g., “lens”) state. (See, e.g., FIG. 4.) This “ramp-up” time, or “rise time,” is usually measured in a few milliseconds or less. In aspects, an electronic circuit will “trigger” the activation of the aMLA and then, after a preset activation time has passed and the aMLA has settled into or achieved its “on” (e.g., “lens” state), the electronic circuit will trigger the micro display to display (flash or pulse) a virtual image, such as information to be projected into the eye. The display can be of a short duration, on the order of around 30 milliseconds corresponding to an approximately 30 fps, but possibly shorter or longer, such as from 0-10 milliseconds, 10-20 milliseconds, 30-40 milliseconds, 40-50 milliseconds, and so on.
An advantage of operating the micro display in a pulse/flash mode as described herein is multifold. Electrically it enables “overdriving” the light emitting mechanism of the display, which makes the display capable of achieving a brighter (in cases, instantaneous) emission/brightness (in cases, measured in watts/Nits) than would be possible if the display was to operate in continuous emission mode (e.g., a “steady state”). This can be an advantage because it enables most displays to be able to better handle the electrical and thermal load due to an intermittent, e.g., “pulse,” display activation without compromising its performance and lifespan. Additional functional advantages for the TOM described herein, based on, e.g., operation in an intermittent pulse mode (pulsed light), is that the retina of the eye perceives pulsed light intensity as brighter than the same intensity of light emitted in continuous (e.g., non-pulse) fashion, because humans are typically more sensitive to blinking/pulsing lights. Moreover, this pulse mode of operation is well suited to the temporal nature of the aMLA-based TOM architecture, which provides for both an intermittent bright image and a low stray light pass-through, which enables the viewer to more seamlessly perceive both the real-world and the augmented reality information (e.g., virtual image) naturally superimposed on each other in time merging into a combined scene (e.g., motion picture) as seen or perceived by the viewer. Thus, rapid alternating or oscillating between “off” and “on” state and/or between duty cycles allows for the presentation of rapid and sequential presentation of images in an order to create the perception of movement; when overlaid with a real world environment, this allows for creation of AR or MR, for example.
Pulsing the light and synchronizing the pulsed light with the aMLA in the “on” state, preferably after the “rise” or “ramp up” time is complete and the aMLA is at a desired focal length (or optical power), requires less energy than a steady state light and therefore creates less heat, which can be uncomfortable to a wearer using a near eye display system and which can more rapidly degrade the xLED and other system components. The partial duty cycle pulsing and synching also allows for a user or manufacturer to choose different modes of operation or functionality. For example, a user could switch the aMLAs into an “off” state to create a see-through window. A user could use an “on” state to create a two-dimensional virtual image, which is preferable in some cases for virtual text. A user could use an “on” state to create three-dimensional images, such as when different parts of an object are to be perceived as being at different distances or depths from the user; for example, an aMLA from one patch unit showing one part of the object might have one effective focal length (optical power) while another aMLA showing a second part of the object might have a different focal length (optical power), thereby creating a perceived three-dimensional image.
The display pixels may be monochromatic (e.g., a single color such as Red, Green, or Blue) or polychromatic (e.g., capable of emitting any and all of the aforementioned colors).
Different TOMs may have different combination of colors such as RGB and CMY (Cyan, Magenta, Yellow, etc.) to provide for a more rich color gamut and 3D effects. In the case of a single aMLA having a single focal length (optical power) that is wavelength dependent, a different voltage (or current) can be applied to optimize the aMLA to provide consistent (uniform) optical power for each wavelength. For example, each individual wavelength can be emitted in rapid sequence and for each wavelength the aMLA can rapidly adjust its optical power (effective focal length) to provide uniform focusing across all wavelengths thereby behaving like a apochromatic lens (e.g., a lens which has a constant focal length (and therefore magnification) regardless of wavelength). This may enable a realization of a multi-color virtual reality without the additional complexity of using a polychromatic lens.
If the system includes an ambient light sensor, the system can instantaneously or gradually adjust or adapt to changes in brightness, such as increasing or decreasing the duty cycle. In aspects, the duty cycle is capable of automatically adjusting (or in cases being manually adjusted) as a function of ambient light in the environment. In embodiments, when the ambient light is bright the duty cycle will be longer, meaning the pixels will remain activated (and the lenses will have optical power) for a longer period of time compared to the see-through aspect when the pixels are deactivated, the lenses are relaxed, and the system, display, or portion of the display are in a see-through state. (See FIG. 5—showing graphs which are not overlaid but which all share the same time axis, thereby depicting the relative timings of the signals/operations over about three cycles (about a 50% duty cycle in the example of FIG. 5).) While the duty cycle may change (e.g., when the “on” state may be longer in duration than the “off” state, such as in brighter environments), the frame rate of the sequential presentation of images (e.g., the motion picture of virtual images being presented to a user of the system) is capable of remaining constant, thereby allowing the user to move from different ambient lighting situations while not having the video, frame rate, motion pictures, images, frames, or other augmented reality experience negatively affected.
Thus, FIG. 5 indicates that the frame rate (or frame timing 5001) remains constant over time 5002 as it cycles 5003. However, if the wearer of the system moves to a bright or brighter environment, the system will need to compensate by making the virtual images appear brighter to the wearer, which may be accomplished by increasing the duration of the duty cycle, meaning the pixels remain “on” and the lens provides optical power for a longer period of time. As can be seen in FIG. 5, voltage 5004 can applied to the aMLA or switchable lens of the aMLA for a longer period of time, thereby making the lens maintain its desired/instructed optical power 5005 for a longer duration. Similarly, the display pixel(s) 5006 can be activated for a longer period of time when the associated lens has its desired/instructed optical power. This increase of the duty cycle (increase of ratio of “on” to “off” time/state) renders the virtual image(s) brighter and better able to be perceived by a wearer of the system in a brighter environment. Thus, while FIG. 5 shows about a 50% duty cycle, the duty cycle can change based on ambient light conditions. Consequently, while duty cycles can all be the same length of time, the ratio of “on” to “off” can change as a function of ambient light. In examples, the duty cycle can have the “on” period last longer than the “off” period, such as in a bright environment when a wearer of the system should see the virtual image(s) for a longer duration than the real world environment (when the optical module is see-through or transparent 5007). This is reflected in FIG. 6, for example.
As shown in FIG. 6—which shows the difference between a high or higher duty cycle (also referred to herein as a longer duty cycle) (higher ratio of “on” to “off”) 6003 and a low or lower duty cycle (also referred to herein as a shorter duty cycle) (lower ratio of “on” to “off”) 6002 for a fixed frame rate 6001—in a low or lower light environment the duty cycle is capable of automatically adjusting to a lower/shorter duty cycle, meaning the virtual image brightness is decreased and the see-through state of the system is increased, thereby allowing the user to better see the (dimmer) real world environment. This allows the wearer of the system to be able to better see the real world environment in low light, while also seeing the virtual image(s), all while not having the frame rate negatively affected. More specifically as shown in FIG. 6, in a low light environment, the duty cycle may change the ratio of “on” to “off” state to prioritize the “off” state to enhance light from the real world to enter a wearer's eye; in other words, in a lower light environment, the aMLA or lens of the aMLA is at its desired/instructed optical power for a shorter period of time. Similarly, the display pixel(s) associated with the lens are activated for a shorter period of time, thereby increasing the amount of time the system is in a see-through state and the wearer can see the real world environment. By way of example only, and not to limit the scope of the invention, a shorter duty cycle may be from 10% to 30% of the cycle having the lens at optical power and the display pixel(s) activated (i.e., the “on” state), whereas a higher/longer duty cycle may have the lens at optical power and the display pixel(s) activated (i.e., the “on” state) between 70% and 90% of the cycle.
An aMLA used in this fashion also resolves issues of stray light, blur, or imperfections in seeing a real world environment through the TOM, because the system will have increased transparency when the system is in “off” mode compared to, for example, a system using static MLAs or a system without pulsing light. This increased transparency when the aMLAs are in “off” mode creates for a more realistic augmented reality experience by a user, including when combined with the enhanced virtual image brightness caused by the pulsed light.
In aspects and as understood by one of skill in the art, stray light is light that does not follow the correct or preferred path through the TOM and may produce a glare or background haze that reduces overall contrast of the desired images. The desired image light, in aspects, includes the real world view formed from light from the external world that passes through the transparent areas of the display substrate and the regions between lenslets on the MLA, especially in the case of a static MLA.
In embodiments, a desired virtual image is formed from light emitted by a display pixel or pixel patch, for example, and then directed through its patch unit lenslet to the eye forming the retinal image. Real world light that passes through a lenslet and is redirected is one form of stray light. Another form of stray light is display light that passes through the region between lenslets and is therefore not focused. Also, light from a patch unit pixel or pixel patch that passes through an adjacent or distant patch unit lenslet (and, in cases, misses its own patch unit lenslet) will be focused incorrectly and is considered stray light.
In embodiments, the invention provides a gray scale (transmission) transition from the periphery of the display patches that start opaque at the edge of the opaque display and gradually transition to fully transparent over a distance of about 10-50 wavelengths of light, resulting in reduced edge diffraction effects. Such a gradual transition can be realized through gradient metal other coating, or hair-like extensions emanating from the edge of the display area which are gradually reducing in width the farther they extend beyond the edge of the display, resulting in a net perception of a gradual increase in transparency along their extension away from the opaque display edge. This is capable of reducing the spurious (stray) light that will diffract from the edges of opaque display patches.
In embodiments, a pixel's or pixel patch's emitted light may be directed through a refractive, reflective, and/or diffractive TOM lens or lenslet. In embodiments, the lenslet may be fabricated as a curved surface on an optically transparent substrate. The surface may have a spherical, aspherical, or other arbitrary mathematical description. The lenslet could also provide focusing capability by dynamically adjusting its power generating properties such as index of refraction and/or curvature structures. The lenslet may be composed of multiple layers of material or a single material. A diffractive or holographic element may direct the light using wave interference methods. The lenslet may comprise a single surface on a supporting substrate, or be composed of multiple surfaces on dual sides of the substrate or multiple substrates. The apertures of a multiple component lenslet may be oriented in line with each other, or not. The lenslet or lenslet set may be decomposed into multiple areas with intervening transparent or shielding areas. The lenslet apertures may be circular, square, hexagonal, or any arbitrary shape for optimum Image quality while minimizing stray light.
The use of Liquid Crystals (LCs) is one way to realize an aMLA by means of electrically switching the LC's index of refraction. A number of different LC technologies may be used separately or in combinations, these are, for example, conventional nematic or smectic phase and cholesteric liquid crystals. Additionally, in embodiments herein, polymer dispersed (or alternatively encapsulated) LCs (PDLCs) as well as their nano-scale variety (nPDLCs) may offer advantages for construction of aMLAs, as the nPDLCs are polarization invariant and therefore can utilize unpolarized light from conventional displays such as OLEDs and iLEDS, by way of example. Additionally, “blue” phase LCs may also possess desirable polarization independent properties, in aspects.
In FIG. 2, a non-limiting embodiment is shown wherein when voltage is applied to a lens comprising liquid crystals 2001 embedded in a shaped material region 2002, the liquid crystals manipulate light moving through the lens (e.g., change the lens' index of refraction) such that the lens region has optical (e.g., focusing) power, whereas in FIG. 3, when voltage is removed from the lens comprising liquid crystals 3001, the lens region 3002 has the same optical properties as the surrounding material and it becomes see-through.
All of the above LC variations can be employed to construct conventional aMLAs (e.g., refractive lenses), as have been described herein, as well as flattened lenses such as Fresnel, diffractive, and holographic aMLAs. Further, all of the above lens technologies maybe used separately or in combination in order to realize optimal aMLA performance.
In additional to LCs, other technologies can be employed for fabrication of aMLAs; these include, but are not limited to, Electrowetting, Electrostatic, Ferrofuidic and Dielectrophoretic, and pressure actuated Liquid Lenses. Various micro-mechanical variable focus lenses may also be used such as Elastomeric Membranes, which are stretched or compressed by mechanical means. Chemically ion activated lenses and lenses that utilize the various Acousto-Optical effects can also be employed as and/or in aMLAs.

Electrowetting (EW) aMLAs

EW lens' functionality relies on the ability to vary the surface tension of liquids via applied voltage, in aspects. For a given liquid drop, its surface tension generates a predictable radius of curvature which in turn refracts light either in convergent (or divergent) fashion, with the former creating a functional equivalent of a positive lens.
With proper shaping of the container holding the liquid, a negative lens may also be realized, which in combination with a static (or active) positive lens may provide a range of tunning as needed to realize the functionality of the aMLA.
For example, variable voltage can be applied to a pair of electrically conductive liquids to change the surface tension and therefore the radius of curvature via a change in voltage. The result is an effective lens of variable optical power. In cases, such control over lens optical power can be used to vary the lens's optical power from zero (e.g., flat non-power plane window) to a preset value as needed to achieve a desired (e.g., effective) focal length (“efl”) (and/or magnification). One can also introduce diversity to the efl resulting in a plurality of focal planes perceived by the eye to be located at different distances in the far field which, when combined with their associated images, will result in the eye-brain system constructing a three-dimensional image by merging a series of focal planes rapidly displayed sequentially in time similar to how humans perceive motion pictures through rapid temporally multiplexed images arranged to be sequential in time at frame rates as low as 20 frames per second (“fps”), although preferably at around 30 fps or higher.
In aspects, multiplexing refers to a method by which multiple analog or digital signals are combined into one signal over a shared medium. The aim is to share a scarce resource. Therefore, several signals or channels can be combined together and then separated at the receiver end. For example only, radio multiplexes several channels on an electromagnetic spectrum by assigning each channel its own frequency. Then a radio receiver can choose the channel it wants. By way of example only and non-limiting in terms of the current application's scope, time multiplexing is in some aspects similar to having a freight train with several box cars, wherein each car represents a slice in time. A portion of a signal is concentrated and assigned to a car. Upon delivery, the desired signal is extracted from each slot/car and recombined.
With respect to the currently described multiplexed system described herein, the system assigns time periods when the display (e.g., display pixels) is enabled or activated, and time periods where the real world is viewed through, for example, the aMLA. Preferably the system does not want a user's eyes to extract, see, or perceive each individual time slot. Rather, the system preferably provides a continual virtual display and continual real world view. Thus, the time periods of the display, for example, are presented rapidly and sequentially (in order) to create the perception of a moving (or alternatively “live” (as opposed to static)) virtual image/object, in embodiments. These are presented along with rapid portions of time when the system is see-through. When you combine rapid periods (alternatively interval durations,) of display and rapid periods of the user being able to see the real world, it creates an augmented reality experience wherein a user perceives a seamless or near-seamless moving virtual image, in aspects, overlaid (or superimposed) over the real world. However, if one was to review the electronic control signals, there would exist time slots assigned to the virtual display (a frame, for example) and the remainder of the time assigned to the real world view. Therefore, in aspects, the time multiplexed system described herein has two channels. And in aspects, when the frames/images are seen at an “on” state of the aMLA and the display, they are fused and perceived as “on” state animation through the time of “on” and “off” states. The technique/system described herein, in embodiments, takes advantage of the limited ability of the human visual system to perceive high spatio-temporal frequencies.
Using another example, the human eye/brain interaction can demultiplex the time sequence if the frame rate is well below about 20 frames per second. That is, the virtual image appears to flicker at low frame rates. Above that frame rate, the human perceptual system cannot separate the image/frame stream, and it appears to flow from one frame to the next. Thus the real world view and the virtual image information is prepared in a time multiplexed form, but a wearer's perception (eye/brain interaction) is not able to demultiplex the stream and both signals appear combined to be natural and stream simultaneously to the wearer, wherein the continuous image/frame stream is overlaid with a real world view, providing augmented reality to the wearer.
EW lenses can be realized using a number of available liquids. Examples of liquids which can be used are, by way of example, various alcohols, more complex hydrocarbons, both solvents and oils, and water. Mercury is also a candidate, but it is typically not applicable to realizing EW lenses operating in transmission, rather in reflection. Electronically, the EW system operates as a (variable) capacitor that dissipates little to no heat and therefore it “consumes” low power and its response can be in the sub-millisecond range for sub-millimeter class EW lenses.
The MLA technologies described herein can be used separately and/or in combination to optimize image quality and also to minimize undesired stray light.
Turning to particular figures, FIG. 1 shows a possible embodiment of the present invention for the system instructing the optical module to display an image or part of an image 1000. In this example, voltage (or current) is applied to a lens, some lenses, or all the lenses of the aMLA 1001. In response to the voltage (or current) the lens or lenses ramp up to an optical power as determined and/or instructed by the system 1002. The lens or lenses reach the instructed optical power 1003 and the system instructs an associated display pixel(s) to activate 1004, which provides all or a portion of a virtual image to a wearer of the system 1005. Then the system instructs the display pixel(s) to de-activate 1006 and a voltage (or current) is removed from the lens or lenses, or, optionally, a reverse-voltage or reverse-current is applied to the lens or lenses 1007, and the lens or lenses relax 1008, rendering all or a portion of the display/optical module see-through so a wearer of the system can see through to the outside real world environment 1009. This process repeats rapidly to present sequential display images creating a perception of a motion picture overlaying the real world environment, thereby providing an AR experience to the wearer 1010.
